4 TYPEWRITER.

Application filed August18, 1923,.Seria1 No. 658,081, and in Brazil September 14, 1922.

My invention relates to improvements in typewriters and has for its object to provide a typewriter adapted to music writing with or without words.

In the drawings:

Figure 1 is a perspective view of a machine built according to the present invention; Fig. 2 is a perspective view on a larger scale of the carriage for the pa er support; Fig. 3 is a detail view of the sta ruling roll; Fig. lshows the spacing mechanism; Fig. 5 shows a mechanism for operating the paper support; Figs. 6, 7. and 7 show the mechanism for elevating the carriage of the paper support; Fig. 8 shows the arrangement of the keys; Fig. 9 shows the operating mechanism for the ink ribbon; Fig. 10 is an end view partly in section of the paper support.

The machine shown in Figure 1 compr1ses printing characters adapted to print, respec. a base 1, to the front-end-ef-whicha mn-nntive tangular, vertical member '1 is attached, a similar member 1 being attached to therear end of the base, and a third member 1 being attached to the middle part of said base. The members 1, 1" and 1 are arranged 1011"- gitudinally of the machine, being connected to each other by bracing bars 1. Base 1 and members 1*, 1", 1; and 1 constitute the main frame-of the machine.

The machine according to the invention comprises a printing key-board T each of the keys of which operates, by means of asuitable mechanism, a bar, on which are formed, or to which are secured, two or four printing characters. The machine alsocomprises an oscillating key-board T having 29 keys, each, one of which, when depressed, communicates to the support for the paper a rotating motion which is diiferent for each press the latter against the paper.

key. This rotating motion is communicated to the paper support through a mechanism hereinafter described, which causes. said support to move so that the paper may pre' sent the desired line or space of the main staff or the supplemental, upper and lower,

ones in correct printing position.

The machine according to the inventionfurther comprises a stafi rulin roll 3 provided in a recess formed at thegree end of abar 3 (Fig. 3), similar to the bars of keyhoardT. andmounted on the frame soas to oscillate into contact with the ink ribbon, to

3 of the ruling roll may be operated by means of a key or of-any' other manual device as for instance, a stem 4 connected with vertical line.

The bar an arm 3 formed on the-end of bar 3. Be-

tween the rulingroll 3 andthe bar-3 is lines will be ruled on the paper according to the roll which has been chosen to rule either the one or the other stafi. Roll 3 shown in Fig. 3 is adapted to. rule a fivel ine staff, but is mounted on a stem which can be easily removed with the roll; so that a roll adapted to rule a four line staif, i.-e.

the staff for Gregorian music, can be substituted for it when desired.

. The key-board T is rovid'eaWEiTfiv? ,-one,ntnzo,.three, four and five horizon- 'tal lines, thus providing for'the'printing of the lines of the upper supplemental staff and, likewise, of the lower staff of polyphonic -music.

Among the printing characters of keyboard T there are also some adapted to print full or open heads for polyphonic music notes, and a character which prints a short By means of this latter character and by communicating a suitable rotatingmotion to the support for the paper, through one of the keys of keyboard T a vertical line of any desired length can be printed on the paper; for instance, a vertical line connected with a note or a dividing bar of the musical compass. Printing characters are also provided adapted to print one, two, three or four tails corresponding respectively to whole notes,

half notes, quarter notes and eighth notes.

Key-board T is provided also with printing chara ters adapted to print the various pauses, a cidents, 'ligatures, suspensions, clefs, signs and fractions indicating the compass, alphabetical characters, punctuation signs, figures and any other convenient or desired signs. For ligatures there are provided two difi'erent printing characters, one for the initial curve of the ligature and the other l for the final curve. By means of these two characters and of the character which prints a horizontal .line, aligature of any length de-' sired can be printed.

Key-board T also comprises printing characters adapted to print the special notes and signs of Gregorian music; or it may be position.

characters on the bar. This is illustrated in the machine shown in the drawings. In case there are four printing characters to each bar, key-board T will be mounted on a separat member, arranged for vertical motion on the main frame, by means'of a key or the like, the motion of the carriage, in addition, being effected as hereinbefore mentioned. In the lowermost position of the printing keyboard frame, any of the two characters on thebar may be printed according as the support 6; the'p'apenis inilwvg /flriupper In the uppermost position of the, frame, any one of the other two characters may be printed," according to the positlon of the carriage.

The keys of key-board T and T and the forward portions of the bars carrying said keys are positioned forward of member 1 of the main frame. The mechanism or detransversal plane passing through the middle of the series of printing bars when these are in inoperative position. Thus the printing key-board T occupies only one half of the face of the main frame, leavingthe other half to accommodate the oscillating keyboard T Without this feature, the length of the machine would have .to be much greater, and the operator would be forced to have responding bar.

,his arms wide apart to operate both keyboards.

This feature is embodied in the machi e shown in the drawings and consists of a modification of the mechanism, by means ofwhich each key acts on the cor- Inthe machine here illustrated, the printing bars lying to the right of the transverse vertical lplane-passing through the middle of the w through the bars 5 (Fig. 8) of the corre- .splplnding keys by means of'a mechanism w 'ch comprises a link 6 pivoted to the bar" 5 at oneend and pivoted at the other end to vice by means of which each key and its ole series of such bars are operated incest? an arm of a bell-crank 7 which is mounted to oscillate on a fixed bar 7 (common to all the bell-cranks) and the other arm of which is pivoted to one end of link 8 which i has the other end pivoted directly (and not through the parts 11, 12, 13 and 14 shown in Fig. 8) to an arm 9 formed on the printing bar 10. The mechanism for each key of the other half of the whole series of printing bars lying to the left of said vertical plane also comprises .a. link 6, a bell crank 7 and a link 8; but this link 8, instead of being secured directly to arm 9 of printing bar 10, is connected with it through a device comprising a link 11, the other end of which is secured to the end of a shaft 12; mounted to rotate in bearings provided in the main frame (or in a separate frame in case printing bars with four characters are used, as hereinbefore mentioned), and the other end of which is connected with a link 13 which is in turn connected with a link 14, pivoted to arm 13 and to arm 9 of the printing bar 10. Through the use of said shaft 12 each key of one half of the ,rintingkeyboard is positionedatradistance to the right of the transverse vertical plane passing through the pivot of each of the printing bars in saidhalfqand, therefore, the whole of the printing key-board lies to the right of the transverse vertical plane passing through the middle of the whole series of printing bars and thus occupies only half of the space on the face of the machine, leaving the other half of it to accommodate the oscillating. key-board T Oawz'age of the paper supp0rt.(Figs. 1, 2 and 10) This carriage comprises an open rectangular frame 20', Figs. 1 and 2, having at its front and at about the middle of its height a longitudinal member 21 and at the rear, at the same height, another longitudinal member 22. Y

On members 21 and'22 are mounted rolling trucks 23 on which carria e 20 is carried to the right or to the left a ong rails 24,

longitudinally attached to the rear portion of the mainframe between the members l and 1 thereof. The lower side of member 22 is provided with rack teeth by means of which and of the mechanism hereinafter described carriage 20 is pushed backward the desired distance to allow the paper :to be moved to tlaei1 succeeding printing position longitudin y.

Papcr supportr- This support comprises a plate 30, curved cylindrically, with refer ence to the horizontal plane and the'segmentaliarchof curvature of which is of such' a length that the paper-placed on-plate 30 presents a surface large enough to take in the printing of the main staff and of the supplemental on'es, according to the. rotary motion of the support for the paper under the action of the keys of key-board T Plate 30 is faced with leather. rubber or any other suitable material to provide a yielding surface and is secured at its ends to discs 31, 32 subroll I 35.

stantially circular in shape. The disks 31,32 are pivoted at their centers to the upper forward corners of carriage 20 having secured to them the ends of a curved rear plate 33 and those of a curved front plate 34 which with plate 33 forms a tapering guide-way forthe paper when the latter is inserted in the machine. This guideway directs the paper to the lower side of a rubber roll 35 (Fig. 10) rotatably mounted in the disks In the latter is also rotatably mounted an upper rubber roll 36 similar to roll 35. Both these rolls.'35 and 36, lie parallel to the axis of rotation of the disks. The axles of rolls 35, 36 project outward from disk 31 each of them having at its end a toothedwheel 37 (Fig. 2). The wheels 37 are of equal diameter and each mesh with a larger wheel 38, concentric with the axis of rotation of disks 31, 32 and manually operable by means of a knurled knob 39. A rubber roll 40 (Fig. 10) of a diameter smaller than those of rolls 35, 36, but of .equal length therewith, is mounted to rotate on the free ends of two arms 41, attached to a shaft 42 rotatably mounted in disks 31, 32'and provided with springs holding roll 40 in contact with of the rubber roll 35. j

A rubber roll 40 (Fig. 10) similar to roll 40 is mounted to rotate freely on the free ends of arms 41 secured to an axle 42 rdtatably mounted in the disks 31, 32 and provided with springs which tend to push roll 40F in contact with the upper face of roll 36. The axle of roll 40 projects outward from disks 31, 32. having at its ends handles 43 for manually moving roll 40*, against the'action of the springs, away from roll 36.

Axle 42 also projects outward from the disks 31, 32, having at its ends handles. 44 for manually moving roll 40 away from the lower side The sheet of paper is inserted into the tapering guide 33-34 till its border contacts I with the lower side of roll 35, when roll 40 dles 44 and is moved away by means of one of. the hanknob 39 turned; roll 35 then taking hold of the paper between itself and roll,40, the latter being released to permit the springs 41 to act on it. The paper is moved. under the lower edge of the curved plate 30 and past it. The sheet of paper is next pulled up by its projecting lower edge,

- When the end of the sta which. is inserted between upper rolls 36 and 40 so that the paper is stretched on'the plate 30 and held in proper position for the printing of the musical signs on -the first main \staif or on the 'su plemental ones.

. Mechanism, for operating the paper 9147- port by means of the oscillating key-board.- (Figs. 2 and 5). To each disk 31, 32 of the paper support is pivoted an arm 45 extend- 47, parallel .to the axis of rotation of the paper support and located somewhat below; the plane of the rails 24 on which travels the carriage of the paper support. To each counterweight 46 is rigidly connected an arm 4'7 which projects forward. Arms 47 are pivoted on a longitudinal bar 47 secured to the front uprights of the carriage. Round bar 47 passes through an opening 48 in the upper end of a stem 48 (Fig. 5). Opening 48 is fitted with a sheave 49 on which bar 47- slides, the upper side 'of the bar being quite close to the upper side of o ening 48. Stem or bar 48 is mounted to move vertically on an suitable guide-ways provided in the main frame of the machine 'andlocated in the vertical transverse plane passing through the middle of its frame, At'the lower end,

stem 48 has a vertical slit 48 in which is lodged a pin 50 secured to the rear end of a double lever 51, arranged in a nearly hori- Zontal position in the said vertical transverse plane. Lever 51 is mounted to oscillate about the end of a longitudinal shaft 52 mounted on chairs 53, 53 resting on base 1 of the machine. On the other end of shaft 52 is mounted to oscillate an arm 54, the free end of which is rigidly connected to the forward end" of lever 51 by a longitudinal shaft 55, oneach end of which is mounted to oscillate an arm 56 directed downwards.

To the lower end of each arm 56 is pivoted the rear end of an arm 57 which lies nearly horizontal and the forward end of which is mounted to oscillate about a longitudinal is mounted on chairs 65 of the base 1 of the shaft 58 mounted on ,chairs 59 resting on machine. Each key 61 is held in inoperative position by a spring (not shown) which acts on the rear end of lever- 62. Each lever 62-is provided with a screw'65 the lower end of. which, when the key 61 is depressed,

causes the paper support to oscillate, bears on theupper face of plate 60 and, asthe key is. furtherdepressed, acts on saidplate so as to cause the arms 57 to oscillate;downwards. Arms 57 through the. members '5656 514-54, 48 cause bar 47 to descend and, as

this bar is connected to the counterweights 46 of the arms 45, pivoted on disks 31-32 of the paper support, vthelatter. oscillates wa y into a position determined by the extent of the operative portion of the angular motion of key 61 which is in turn determined by the length of that portion of screw 65 which extends below the key-bar 62. As hereinbefore mentioned, each key 61 communicates to the paper support an angular motion which is different for each key. When one of the keys 61 is depressed to bring the paper into the propen position for printing a note on a "line or a space of the staff, the key should be held depressed,

while the printing character ofthe line or on chairs of the base 1 of the machine. Arm 73 has an extension 7 3 which forms with it abell crank lever 78, 7 3 the rear end 73 of which is connected by a link 74 to one arm of bell crank lever 75 (Fig. 9) pivoted on a fixed chair, the other end being provided with a pair of pawls 76, adapted. to rotate a cog-wheel 77 mounted on one end of a horizontal shaft 78 mounted to rotate on fixed chairs. On the opposite end on the lower end of a vertical shaft 81' sides-of the upper portion of the main to the base of the machine.

of shaft '7 8 is mounted a conical pinion 79 meshing with a similar pinion 80 mounted (Figs. 9 and 1) mounted to rotate in the frame of the machine. The, upper portion of shaft 81 extends above the bottom of a cylindrical box 82 in the center of which there is an aperture through which passes the shaft 81. To the upper portion of shaft 81 is fitted the reel on which the inking ribbon is -wound coming from another reel located in a similar cylindrical box 83 (Fig. 1). 7 Boxes 82, 83 are located on op site-- ame of the machine. The rear end of the bell crank lever 73, -73 hereinbhfore mentioned, with which the link 74-. is connected, is by means of a link 83, connected with one arm of the bell crank lever'84mounted to. oscillate yertically on -a .fixed chair 85. v

The other armof lever 84 rests on the upper free. end of a curved yielding strip of metal 86 the lower end of which is secured When all the keys of the oscillating key-board T are in inoperative position, stri 86 acts on bellcrank lever 84 so that e latter, through link 83,'causes arm 73 of the bell-crank ,lever 7 3-73 to descend, till the upper side Jof arm 73 rests farm, as well as against a stop, thisclatter e $111173" and -bar 72,-

lying then horizontally or in normal position. Each of the vertical stems (connected to the levers 62 of the keys 61 of oscillating key-board T has at the upper end a head 70*. Each ofthe stems 70 is of such a length that, when one of the keys 61 is depressed to cause the support for the paper to oscillate, its corresponding stem 70 is pulled down through its hole 71 in bar 72,

until the head 70 of'the stem rests against the upper side of bar 72 and, when the key is further depressed, stem 70 pulls down the bar 72, against. the action of strip 86 and then the bar 72, by means of the mechanism hereinbefore described, causes the rotation of pinion 77 (Fig. 9) and thereby of the horizontal shaft 78. Shaft 78, in turn by means of the conical gears 79, 80, causes the rotation of vertical shaft 81 and with it that of the reel on which the inking ribbon is being wound, the ribbon passing through lateral slits, 82, 83 in the boxes 82, 83 to a guiding member 90 1) provided with a foursided'opening 91 where a portion of the ribbon is exposed, 'to the action of a printing character by the depression of any one of the keys of the printing key-board T Guiding member .90 is mounted and directed for alternate vertical motion, at the upper end of its travel presenting the ribbon 1n printing position and at the lower end carrying it below printing position, so that the character just printed becomes visible.

To move the guiding member 90 up and down, a link mechanism is provided connected with an arm rigidly secured to a frame located under the printing key-board,

T so that it can be operated by any of the printing keys. This frame is mounted to oscillate about a horizontal bar mounted on fixed chairs. Normally, guiding member is maintained in its lowermost position by means of a spring. When any 0 the printing keys is depressed, it acts in opposition to the spring, and through the-connections just mentioned, to raise member90 to its uppermost position. This mechanism is not shown as its operation is easily'understood. Elevating mechanism for the carriage of the paper sapport.-(Figs. 6, 7 and 17%). As

hereinbefore stated, the/carriage of the paper support, when in its/normal position, allows the printing of one of the characters of each printinglbar of the printing key board T but it ma e raised to allow the printing of a secon character on each bar.

Y The mechanism through which thisis accomplished isas follows: A. manual lever is secured to one end -of a horizontal shaft 101 which oscillates in chairs resting on the base of the machine. To the other end of shaft 101. is secured an arm 102 which is connected by a which is pivoted to the lower'arm of a hell 103. to one end of a 'transverselower. bar 04 the o posite end of with the upper end-of a crank lever 105 pivotedat106 to a vertical chair 107, the upper end of which is located somewhat below the round bar 20 which is the lower horizontal rear member of carriage 20 of the paper support (Fig. 2). To

To the upper end of chair 107 is pivoted the upper end of a bar 110, and to this upper end of bar 110 is rig- Fig. 2, which-is the lower horizontal front .idly secured the rear end of a transverse bar 113 to the front end of which is rigidly secured a bar 114.parallel to bar 110, on the lower end of which bar 114*is pivotedthe forward end of a lower transverse bar 116, of greater length than that of the upper transverse bar 110 and the rear end of which is fpivoted to the lower portion of the chair 10 Intermediate the ends of. link 103 is pivoted thereto the forward end of a link 117 the rear end of which is pivotally connected ink 118, the lower end of which is pivoted to a fixed chair on the base 1 of the machine. On base 1 is also equal angle in the direction of arrow b. Link 102 in turn "causes link 103 to move in same direction this latter link operating link 104, which causes curved lever 105 to describe an angle in the direction of arrow 0, carrying link 108 into the position shown in Fig. 7. Link 108 pivoted on bar'110 causes the latter to move through an angle, arm 113 moving through an equal angle in the vertical direction, upwards, the direction of arrow X and thus, by means of the sheave provided on the forward end. of I13,'the

longitudinal lower member 20 at the front of the carriage or frame 20 is, raised.

The round bars 47 and 47 must be raised simultaneously; otherwise the paper support would get out of level. The manner in which bar 47 is raised simultaneously with 'bar 47" by the actuation of hand lever 10 alone, shall now be explained. I

I The forward motion of link 103 is communicated to link 117 pivoted to it. Link 117 through-fork 117 near its rear end transmits its motion to the lower arm of bell crank lever 124 which'is oscillatedin the direction of arrow H, Fig. 7, going to'the position shown in Fig. 7

By this motion, the upper arm' of bell mounted a chair 1-19 to which is pivoted ar crank lever 124 causeslink 125 to move from by means of which the arm 51, Fig. 5, of.

the oscillating mechanism is held in the slot 48 of thevertical stem 48 whichcauses the paper support to oscillate, the stem 48 being located between 51 and 124. The lower arm of hell crank-124 is provided'with a roller by means of which it can be operated by a fork formed on link 117.

When the carriage is in the lowermost position, Fig. 7, pin 124 islodged in a recess in the 'upper part of slot 48 where it is located so as to oscillate. vWhen the carriage is raised for the purpose hereinbefore mentioned, pin 124 must come out of the recess, otherwise it would hinderthe raising This is done automatically manner.
